Power End Accessories connecting rod

Connecting Rod The connecting rod joins the piston to the crankshaft and transfers piston reciprocating force to crankshaft rotation. The small end of the connecting rod reciprocates and the large end follows the crank pin rotational pattern. For this dynamic movement, the connecting rod should be as light as possible while maintainin0 its rigidity. The connecting rod (Fig. 3.77A and B) is basically of two ring forms, which encircle the piston pin and the crankshaft rod journal. From each of these ring forms a tangential fillet blends into a tapered H-section of the rigid rod strut. Each connecting rod is fastened to the piston by piston pins and to the crank pin (journal) of the crankshaft by a plain split bearing.
